Launchers sit in the corner during PSE Burst, anyone who is NOT a launcher, kills absolutely nothing during PSE burst, and should use the Sit emote, and go Afk.
No.... Seriously.... If you don't have a launcher, sit in the same spot as launchers, and go Afk, while work is being done. Especially during Ark Boost Event.
Edit: I'm 75 Force, Tek, Ranger, and soon to be Gunner rofl... Sorry, grinding is a "Launcher thing"
